SLASEG6B May 2018 – June 2020 TAS3251
Because the TAS3251 device is a highly configurable device, numerous modes of operation can exist for the device. For the sake of succinct documentation, these modes are divided into two modes:
Fundamental operating modes are the primary modes of operation that affect the major operational characteristics of the device, which are the most basic configurations that are chosen to ensure compatibility with the intended application or the other components that interact with the device in the final system. Some examples of the operating modes are the communication protocol used by the control port, the output configuration of the amplifier, or the Master/Slave clocking configuration.
The fundamental operating modes are described starting in the Serial Audio Port Operating Modes section.
Secondary usage modes are best described as modes of operation that are used after the fundamental operating modes are chosen to fine tune how the device operates within a given system. These secondary usage modes can include selecting between left justified and right justified Serial Audio Port data formats, or enabling some slight gain/attenuation within the DAC path. Secondary usage modes are accomplished through manipulation of the registers and controls in the I2C control port. Those modes of operation are described in their respective register/bit descriptions and, to avoid redundancy, are not included in this section.
